T 0 all whom 2' may concern:

Be it known that I, GEORGE LEACHMAN, a citizen of theUnited States, anda resident of New Cumberland, in the county of Hancock and State of estVirginia, have in vented a new and Improved Portable Dark Cabinet, ofwhich the following is a full, clear, and exact description.

My invention has for its object to provide a portable dark cabinethaving a table with I a frame disposed above the table which isconnected with the table by a hood, the rear of the frame being hingedto its forward portion so that the rear of the frame with the rear ofthe hood may be raised to per mit the operator to place on the table thematerials desired, and to enter the hood through an opening in thebottom thereof at the rear of the table.

Additional objects of the invention will appear in the followingspecification, in which the preferred form of my invention is described.

In the drawings similar characters of reference indicate correspondingparts in all the views, in which Figure l is a front elevation showingmy invention; Fig. 2 is a side elevation of Fig. 1; Fig. 3 is asectional view on the line 3-3 of Fig. 2; Fig. at is an enlargedfragmentary sectional view showing the means for supporting the table Onthe standards; Fig. 5 is a perspective view showing the means forsecuring the hood around the waist of the operator; and Fig. 6 is aperspective view showing the frame.

By reference to the drawings, it will be seen that two standards 10 areprovided, these standards 10 having adjustable collars 11 which may beheld in adjusted position by means of clamps 12, a table 13 being provided and having at its sides resilient clamps 14 for embracing thestandards 10 above the collars 11 so that the collars 11 will supportthe table by means of the clamps 14. The table 13 may be readily raisedwhen desired and it may be held in any position desired by means of thecollars 11 which may be secured to the standards in the mannerdescribed. The resilient clamps let are disposed at the rear of thesides of the table 13, it being possible to move the table 13 rearwardlyto readily disengage the table from the standards. A hood 15 is securedto the sides and the front and the rear of the table 13, this hood 15being supported above the table by means of the frame 16, the frame 16having a bracket 17 with an opening 18 through which the top of thestandards 10 are disposed, the standards also being disposed through theorii'ices 19 in the flanges 20, each secured to the sides of the forwardportion of the frame 16. The standards 10 have shoulders 21 which engagethe flanges 20 at the sides of the orifices 19.

As has been stated, the hood 15 is disposed over the horizontal frame16, the forward portion of which is supported by the standards 10 in themanner described. The rear portion 22 of the frame 16 is hinged at 23 tothe forward portion of the frame 16 so that the rear portion 22 of theframe may be raised with the rear portion of the hood to permit theoperator to place materials on the table 13 through the opening 24 inthe bottom of the hood 15 at the rear of the table 13. When the desiredmaterials have been placed on the table 13 through the opening 24:, theoperator then inserts the upper portion of his body through the saidopenings, this being easily accomplished since the hood 15 will besupported by the portion 22 of the frame 16 which has been raised as setforth. hen the operator has inserted the upper portion of his bodythrough the opening 24 the straps 25 secured to the hood 15 at theopening 2 1 are drawn together and are secured by means of the fasteningmembers 26. It will be noted that the clamps 1 1 are to be constructedof sufficient strength to hold the table 13 in adjusted position afterit has been raised or lowered and without any support from the collars11. In this way the operator may adjust the table while operating withinthe opening 2% in the hood 15.

At one side of the hood 15 there is, preferably, an opening 27 with atube 28 secured to the hood 15 at the sides of the opening, the tube 28having a mask 29 which may be secured over the face of the operator topermit the operator to breathe fresh air while working within the hood.

The table 13 has a leaf 13 which is hinged at 13 to the table. This leaf13" may be folded against the table when the cabinet is not in use.

The ruby glass Window 27 is hinged at frame,

27- in a frame 30 secured in an opening31 in the hood 15. a

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
